LASER Safety Measures
The RadiSense uses a high-power LASER to supply energy to a remote measuring device. The
wavelength of this LASER is approximately 808nm. This infrared laser is invisible to the human
eye.
During normal operation, exposure to LASER radiation is not possible because the RadiSense
uses a fibre-coupled closed loop system with Automatic Laser Shutdown (ALS). However, we ask
that you comply with the following precautions for your own safety:
NEVER look into any of the fibre optic connectors. The LASER emits a
beam that is invisible to the naked eye. Such light may cause permanent
eye damage. Avoid eye or skin exposure to direct or scattered radiation.
Assign a ‘LASER safety officer’ in your company. The ‘LASER safety officer’ is
responsible for reviewing the safety precautions.
Check and connect all fibre cables before activating the system.
Do not activate the system if the fibre optic cables show any sign of damage or
tampering.
The RadiCentre
system is equipped with a remote interlock system. This interlock
system prevents inadvertent LASER radiation. For example, to prevent LASER
radiation when someone enters a shielded room and steps on a fibre.
The remote interlock connection should be connected to an ‘emergency master
disconnect’ and in series with the room door or fixture interlocks.
A visual ‘LASER ON’ indicator LED will light up when the LASER is activated. This
LED on the front panel of the RadiCentre
system serves as a reminder to the
operator that one or more LASERS are switched on.
